How Not To organize an Open Air concert for 3.000+ visitors

(Inspired by yesterday's visit to Eric Clapton on Bowling Green, Wiesbaden, Germany, Earth)

1. Create different visitor areas for people with seat tickets at the front, stand tickets, and seat tickets at the back. Separate these areas with solid constructions, requesting visitors to show their ticket at each border and disallowing entrance for people with the wrong ticket category. Hey, there's restrooms in each area, even in yours! Just on the other side of that crowd!


2. Create a separate entrance for each class of ticket holder. Plus, don't place any signs telling people what to do. After all, it's funny for 60-100 € paying customers to queue up for 20 minutes just to be told they found the wrong entrance. Isn't it?


3. Don't care about sizing the grill or drink stations. People do like queues, don't they? And wouldn't more than 4 grill/drink people per 500 visitors impact the relaxed atmosphere?
